Microfluidic Cooling Cuts the Layers Between Die and Coolant
Embedded microchannels remove interface layers, but pumping and pressure set the cost.
Material Compatibility Coolant Sheets Split on Aluminum Use
Three coolant loop sheets ban, condition or allow aluminum, and one test shows why.
Data Center Heat Rejection and the 43 °C Dry Cooler Ceiling
Every hop from cold plate to outdoor coil costs kelvin, and the exit sets the ceiling
Latent Heat Cooling Pays Off Until Vapor Quality Nears 0.7
Boiling carries 8 to 54 times more heat per kilogram, until vapor quality nears 0.7
Rack Density by Cooling Type and PUE by Method, Compared
Stated rack loads, PUE labels and retrofit burden across cooling methods, side by side
H100 Thermal Throttling Starts at a Margin, Not at 87 °C
Where H100 thermal throttling begins, and why 87 °C is not the number
Cooling Capacity Calculation Turns CDU Ratings Into Delta T
Eight CDU ratings work out to secondary rises from 8.3 K to 28.2 K, not one rule
Liquid Cooling Standards Fix the Coupling Fit, Not the Flow
A UQD04 coupling can pass OCP's v2 spec at Cv 1.1 or 1.6. The drop differs 2.1 times.
GPU Power Consumption Trend From 700 W Chips to 142 kW Racks
Chip ratings doubled. GPU count per rack pushed the load from 40.8 kW to 142 kW.
